Genetic Counseling

Posted 5/16/2017

Posted in

  As the science has exploded, the role of genetic counseling in cancer care has also grown. It was not long ago that genetic counseling for cancer patients really meant testing for the BRCA genes that raise a woman's chance of developing breast and ovarian cancer. There are now many more identifiable genes, and much more that can be learned. The question hovers, however: what can be done with the information and when is it helpful to know?

  For example, I have a patient who has tested positive for the PTEN mutation that raises her risk of a number of cancers. This means that her doctors have suggested that she undergo regular screening for several of them, and she feels increasingly that she is too much at the hospital and too focused on cancer possibilities. Unlike some genes that guarantee illness, e.g. Huntington's Disease, cancer mutations increase risk, but do not signal inevitability.

Genetic Counseling and Cancer: Now and in the Future

An individual’s risk of developing some types of cancer can be increased by specific genetic changes, or mutations, which are passed down from parents to their children. This increased risk is called hereditary cancer risk.

Genetic testing will allow you to learn if you have genetic mutations currently known to be linked to hereditary cancer risk. share on twitter It will not tell you if you will get cancer, only whether you have a higher risk of developing cancer. The results of genetic testing can also help guide decisions about screening or treatment options. But the decision to be tested is complex, and learning the results can bring up many different emotions. Luckily, genetic counselors are here to help.

Tiffani DeMarco is a certified genetic counselor and co-manager of the Cancer Genetics Program at Inova Fairfax Hospital in Fairfax, Virginia. In this expert podcast, she explains how genetic testing has evolved over time and answers some common questions about the role of a genetic counselor.

Genetic testing can help estimate a person’s chance of developing cancer in their lifetime based on changes, or mutations, in their genetic code. Genetic counselors are specially trained medical professionals who can assess and advise people on their individual risk of cancer based on their family’s history of cancer and the results of genetic testing. In this podcast, Tiffani DeMarco explains the role of a genetic counselor and discusses how genetic testing has changed over time.Genetic testing can help estimate a person’s chance of developing cancer in their lifetime based on changes, or mutations, in their genetic code.
